Why won't Windows 7 work on my Setup!

Last response: in Windows 7
Share

I bought Windows 7 in the middle of Jan. this year and it don't work on my PC. It will install but after the install I lose all video from my Graphics Card. But XP doesn't have that problem like 7 does. I have called Microsoft multiple times about the issue and they have not figured out the problem. Is it a problem with my GTS250 or what else would the problem be. I also have had all my other hardware tested and have found no faults to it. I would like to use windows 7 but Microsoft can't figure out the problem. So any and all help would be a blessing in this matter. Thanks.

Reseat the video cable at both ends (monitor and PC) and boot into safe mode. See if you get any video there.

Edit: This seems more like a driver problem than something Windows 7 specific. I've never seen anyone has this problem before.

I have reset the cable at both ends and I get video in Safe Mode but that is due to it is using generic drivers Microsoft said. I also tried both DVI ports on the Video Card and had the same results.

My brother had a similar issue, what he had to do was install vista, then the vista drivers, then install win7 over it, it's not technically a clean install, but from what I understood it worked. Not the perfect solution, but a solution.

Keep in mind that would only work when it comes to hardware from companies like AMD and Nvidia that have unified drivers. If an OEM wrote a specific driver for each operating system...

Was this an "upgrade" or "clean install" ? Clean install means you formatted your HD.

If upgrading, did you uninstall video card drivers before upgrading ?

Diod you let MS Windows Update install video card drivers (Just say no !)

Have you tried ?

1. Uninstalling all nVidia drivers
2. Cleaning registery of all things nVidia w./ CCleaner or driversweeper.
3. Resinstalling latest nVidia GFX drivers.



I don't mean to sound like a hard ass but yall are telling me the same that I went threw with Microsoft. I was on the phone for over 3 hours with them. So I was hoping yall would come up with that Microsoft didn't come up with.

Forgetfull,

You were so close with the safe mode bit and the generic drivers of windows.
Since you said yourself in safe mode you get a display on your monitor instead of a black screen.

What it tells me is Forgetfull, it is likely you also have a motherboard with intergrated graphics chip.
And also a vga output for it on the back.

It is likely in that case that windows 7 may be using that instead.
And in order to make it work on your GT 250 card you will need to disable the intergrated graphics card in your bios settings.

To be honest i have seen this before and it something you forget about sometimes.

What about you power supply? Mine did the same thing on a new build, I swiched some cables around, and it worked. I thought it was the drivers too, but it was the PS, and windows 7, I think someone posted about it earlier.

So with my PSU I need to use the other 6 pin Express connector? Also my onboard video on my mainboard has an auto disable I think but don't know. Also since my mainboard has Hybrid SLI cold that be an issue to or not.

Easy check, boot into windows and plug monitor into onboard graphics connector, if it works, then go into bios and change to primary display on Pci and disable onboard, not leave auto, disable!

Best solution

Moricon is also right with what he has said in his post,
It could be as simple as changing a setting to pci-e slot as your primary graphics card in the bios.
I would also check that you do in fact have the extra power feed from your psu = 6 pin pci-e power connector on your GT 250 graphics card, see if it is loose.
With out it in it is also likely to be the cause of black screens, just before it goes to load into windows 7, and to the desktop.
The reason for it is windows xp, infact used a 2d driver for its desktop display of windows xp.
Windows 7 uses a 3d driver to display the desktop. in 3d mode the GT 250 card will need more power to run.

All i can hope is this was a bit more help, than from MS.
And that you now have a good idea of how to fix this problem.
Let me know how you got on with it.
